Infrared sensor switch principle Infrared sensor switch installation requirements

Inductive switches include infrared sensor switches , microwave sensor switches, and ultrasonic sensor switches. This article focuses on the human body infrared intelligent sensor switch, which is a switch that is automatically activated when someone passes the infrared sensing area. The main component of human body infrared sensor switch is human body pyroelectric infrared sensor. Human pyroelectric infrared sensor: The human body has a constant body temperature, generally at 37°C, so it emits infrared light with a specific wavelength of about 10 μm, and the passive infrared probe works by detecting infrared radiation emitted by the human body at about 10 μm. So the infrared sensor switch is not good, what is the working principle of the infrared sensor switch ? Here is the answer to the above questions to reveal the answer one by one.

Infrared sensor switch definition

A switch that is automatically activated when someone passes from the infrared sensing zone. The main component of human body infrared sensor switch is human body pyroelectric infrared sensor. Human pyroelectric infrared sensor: The human body has a constant body temperature, generally at 37°C, so it emits infrared light with a specific wavelength of about 10 μm, and the passive infrared probe works by detecting infrared radiation emitted by the human body at about 10 μm.

Infrared sensor switch principle

The main component of human body infrared sensor switch is human body pyroelectric infrared sensor.

Human pyroelectric infrared sensor: The human body has a constant body temperature, generally at 37°C, so it emits infrared light with a specific wavelength of about 10 μm, and the passive infrared probe works by detecting infrared radiation emitted by the human body at about 10 μm.

The scope of application of infrared sensor switch is suitable for automatic lighting, ventilation and other purposes in corridors, corridors, warehouses, garages, basements, toilets and other places. It truly reflects the modernization of building intelligence and property management.

  

Infrared sensor switch features

1. Automatic control products based on infrared technology. The person does not leave and is in the activity, the switch continues to conduct; After the person leaves, the switch delays and closes the load automatically, the person is bright, the person is away from the light, friendly and convenient, safe and energy-saving.

2, with zero-crossing detection function: non-contact electronic switch, extending the life of the load.

3, application of photosensitive control, automatic light metering switch, when the light is not strong.

  

Infrared sensor switch installation requirements

Infrared sensor switches work by detecting the presence or absence of infrared light in the human body and are usually installed indoors. The false alarm rate of the human body sensor switch has a great relationship with the installation location and mode. The following should be noted when installing the human body sensor switch:

1. Please do not electrify when installing, and then power on after installation.

2, do not use the super power range.

3, top mounted human sensor switch should not be too high from the ground, preferably between 2.4-3.1 meters. The wall-mounted body-sensing switch can be installed in the original switch and replaced directly.

4, when installing the body sensor switch, should be far away from heating, air conditioning, refrigerators, stoves and other air temperature sensitive sensitive places.

5. There must be no screen, furniture, large bonsai or other partitions within the detection range of the sensor switch.

6. The switch should not be directly facing the window. Preventing the disturbance of the hot air flow outside the window and the movement of people can cause false alarms.

7. Do not install switches, wind tunnels, etc. where there is strong air flow.

Editor's summary: The above is the principle of infrared sensor switch, infrared sensor switch installation requirements related to the introduction of infrared sensor switch, directly by the human body temperature can achieve the switch Oh! It's amazing! However, there are also more requirements for the installation environment.
